Use DEVICE_ATTR_WO for write only attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @wo@ declarer name DEVICE_ATTR; identifier x,x_store; @@ DEVICE_ATTR(x, \(0200\|S_IWUSR\), NULL, x_store); @script:ocaml@ x << wo.x; x_store << wo.x_store; @@ if not (x^"_store" = x_store) then Coccilib.include_match false @@ declarer name DEVICE_ATTR_WO; identifier wo.x,wo.x_store; @@ - DEVICE_ATTR(x, \(0200\|S_IWUSR\), NULL, x_store); + DEVICE_ATTR_WO(x); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> --- arch/mips/txx9/generic/7segled.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/mips/txx9/generic/7segled.c b/arch/mips/txx9/generic/7segled.c index 566c58b..2203c25 100644 --- a/arch/mips/txx9/generic/7segled.c +++ b/arch/mips/txx9/generic/7segled.c @@ -55,8 +55,8 @@ static ssize_t raw_store(struct device *dev, return size; } -static DEVICE_ATTR(ascii, 0200, NULL, ascii_store); -static DEVICE_ATTR(raw, 0200, NULL, raw_store); +static DEVICE_ATTR_WO(ascii); +static DEVICE_ATTR_WO(raw); static ssize_t map_seg7_show(struct device *dev, struct device_attribute *attr,
